==== 1. What and Why ====
\\ 

=== A. What can Chartscale-pi do ===
\\ 
The plugin allows the user to zoom in and out by means of a slider. \\ {{opencpn:plugins:chartscale:chartscal_last.png?direct&}}\\ 
\\ 
=== B. Why can Chartscale-pi be useful ===
\\ 
Normally you use the (+) and (-) buttons or the scroll-wheel of your mouse for zooning in and out. But maybe you prefer tou use a slider. The position of the slider (far left, far right or somewhere in between) gives you a direct indication of the zoom-status.\\

 \\ Click "**OK**" in the Chart Scale Preferences window and then "**OK**" in the Plugins-window.\\ 


Now the Chart Scale slider should appear on your screen.

In this example the slider-button is to the far left. That means "zoom in as far as possible".

And in this example the slider-button is to the far right. That means "zoom out as far as possible".\\
